Flag anomalous execution-trace durations with a z-score against a historical baseline, plus explicit error flags. Runs entirely in your browser.
Bundled sample baseline and traces (edit in src/app.ts and rebuild to try your own):
Known limitations: a simple statistical heuristic (z-score), not a trained anomaly
